Where is the Carburator on a Lawn Mower?

The carburetor on a lawn mower is usually found on the left or right side of the engine. Many times, you will find a black rubber ‘button’ that you can easily push in. This is called the primer. It is used to ‘prime’ the ‘carb’ with gas to make starting a cold engine easier. If you find this, the carburetor is right behind it.
